Above
: bad setting of the trimmers, the carrier and modulation frequencies
are dominant, the amplitude of side bands (C-M and C+M) are roughly 60%
of C and M. Below : best setting I could achieve, now the sidebands are dominant and modulation and carrier are rather low in amplitude though still there ! The amplitude scale is linear, the frequency scale ranges from 100Hz to 10kHz. |
Same
as on the left but with a logarithmic amplitude scale. In this mode some overtone sare clearly visible, due to the harmonic distorsion of these not that pure sinewaves from the Wildcat's VCOs ! |
